Gametap is an online game subscription service. It's $9.95 a month, and there's a bunch of games on there, everything from PacMan to fairly new PC games. You just download a game and start playing, it's pretty slick. It's PC only, but a Mac version is in the works. I don't use it much, but at 10 bucks a month I haven't been motivated enough to cancel it yet :)

Sup, let me just say one thing, from my COLD DEAD HANDS! That's when they'll take my signed TFL CD. I'm still steaming that b.net for TFL never came back up too, despite literal promises to the contrary.
